Pressure can also be adjusted by moving closer or further away from the cleaning surface and by adjusting the spray fan angle as shown.
Angle to the Cleaning Surface
When spraying water against a surface, you can generate maximum impact by striking the surface head on. However, this type of impact can cause dirt particles to embed in the surface and can prevent the desired cleaning action.
The optimum angle for spraying water against a cleaning surface is 45 degrees.
Spray water against a surface at a 45 degree angle to achieve the most beneficial impact force and to efficiently remove debris.
Distance From Cleaning Surface
The distance between the spray tip and the cleaning surface is another factor that affects the impact force of the water. The impact force of the water increases as the tip is moved closer to the surface.
How to Avoid Damaging Surfaces
Damage to cleaning surfaces occurs because the impact force of the water exceeds the durability of the surface. You can vary the impact force by controlling the spray tip angle to the cleaning surface and the distance from the cleaning surface and by changing the spray tip. NEVER use a narrow high impact stream on a surface that is susceptible to damage. Avoid spraying windows with a narrow high impact stream.
Doing so may break the window. The most sure way to avoid damaging surfaces is to follow these steps:
1.Before triggering the gun, make sure the quick connect tip you are using is appropriate for the application.
2.Place the spray tip approximately
3.Vary the fan pattern spray angle and the distance to the cleaning surface until optimum cleaning efficiency is achieved without damaging the surface.
Detergent Application
Note: Use only detergents formulated for pressure washers.Test detergent in an inconspicuous area before use.
Detergents
The use of detergents can dramatically reduce cleaning time and assist in the removal of difficult stains. Many detergents are customized for pressure washer use on specific cleaning tasks. Pressure washer detergents are as thick as water. Using thicker detergents – like dish soap – will clog the chemical injection system and prevent the application of the detergent.
